If I bought a deeded used 2 bedroom lockoff during high or peak season, how well does that trade on Interval International?
Destination Exchange shows what I could do with it.
I don't think it would trade that well in Interval. Las Vegas is pretty easy to trade into. You also have to find out from Diamond how their deposits work for deeded weeks - whether they let you pick the week, or if they assign it randomly. If the latter, the trade power will be lower. I just checked II, and New Years Las Vegas weeks are just sitting online. Also, Diamond charges resort fees for exchangers at their resorts - so many people choose not to exchange into Diamond.
I think the only Diamond resorts that would be good for exchanging in II are the Southern California Coastal resorts, Hawaii resorts, and Myrtle Beach resorts. For SoCal and MB, you would want to make sure you could deposit a prime summer week.
Dunes Village Resort is an affiliated resort that is in Destination Exchange. Summer weeks would exchange very well in Interval. I have never looked for one of these, so I don't have any idea what they might cost. I also don't know how affiliiated resorts work with Diamond. Your best bet for ensuring that a week works well in both Destination Exchange and II is probably Riviera Beach and Spa, and Riviera Shores. But make sure you can make summer week reservations if you purchase a week. Summer weeks in SoCal trade extremely well in II. A deeded Lake Tahoe week that floats in summer is also a good bet for II. I don't know if there are any 1 bedroom deeded weeks there, but they get a Tier 4 if you reserve specific weeks, and any summer week there should trade well in II.
It's hard to find a unit that trades well in II and is also good for Diamond... When you have more vacation time available, you might want to look into getting a non Diamond unit for II trades, and a Diamond unit for Destination exchange trades. Since you have only a few weeks a year now, you might want to focus on getting a week just for II exchanges or just Diamond exchanges.
For II, I think the best week to get is a good Marriott trader. Those are amazing. Marriott Grand Chateau, Desert Springs Villas, Shadow Ridge, and some of the Florida units (I have less experience with those) in Platinum season are great traders. You can lockoff the 2 bedroom units and get 2 weeks vacation in Marriott resorts. We have been able to get Kauai summer and Caribbean spring break weeks with Marriott trades.
